| Abstract: | This paper mainly studies the LED driver circuit used in the car tail lamp which needs to realize the welcome function. It usually has the effect of dynamic steering light, stop light running or breathing, position light breathing or flowing water, which can increase the fun and aesthetic feeling. The LED driver for dynamic welcome tail lamp developed in this paper uses SPI(serial peripheral interface) communication control drive circuit, Buck and LED multichannel driver circuit, which has strong operability and can realize a variety of welcome modes. |
